Expression of a full length type 1 px cDNA is governed by UASt regulatory sequences.
visible, with Scer\GAL4C-765
wing, with Scer\GAL4C-765
wing, with Scer\GAL4ptc-559.1
When expression is driven by Scer\GAL4C-765 wing size is increased. When expression is driven by Scer\GAL4ptc-559.1 the spacing between L3 and L4 veins becomes narrower without changing cell density.
